家里网络经常自动断开！请教大神

Zhuang961208

家里的网络这两天回来发现经常会自动断开。
一开始以为是家里的老tp路由器故障了，换上了K2刷上了老毛子，但是依然会显示这样的问题。
家里网络是 网线→光猫（没有无线功能）→k2路由器拨号pppoe（使用了mac克隆）
然后用一段时间就开始断网，主界面显示ppp等待连接。下午恢复出厂设置之后正常了 ，到晚上回到家看了看k2的日志发现还是中途断网了有一个小时。具体日志如下
大佬们帮忙看看，谢谢各位大佬

前几条日志应该是下午恢复完出厂设置之后时间没校正，然后路由器自动连接了那个网址之后自动校正了
下面16点多的是开始断网的
希望能看懂日志的大佬知道一下我！谢谢各位

有事没事先报障，省事不费钱！

刷个官改试试，如果还断线，那一般就是线路问题了。

我刺激了

之前我这也是这样经常断，后来发展原来是家里电的问题，家里电虚接，可能引起电压不稳，引起猫活着路由器也不稳，可家里电器什么的都可以正常使用，一次下雨停电才知道哪里虚接的，后来接上后就没掉过线了！

联系服务商换个光猫试试，可能是光猫故障！我家之前也是，换光猫后好了

光猫问题呗
